Move through the room until you find a set of double doors; this door is going to open and lots of goons are going to come out, so either take cover or throw your grenades and hide. In any case get rid of them, as per usual, and move straight ahead until you find a room labelled ‘Laboratory’ on your left. Be aware that the place will be absolutely filled with Black-ops, so you need to watch your step. Pick up everything on the table, after you’ve eliminated everyone, and get ready for more fighting as you move on.
When you get to the windows, by the broken vending-machines, ops will start firing from downstairs: do what’s necessary and jump down. Activate the elevator and wait (guys will still attack you). Once the door’s open get in and activate the panel (E key). They’ll soon realise your tricks and stop the elevator, but it will stop mid-floor; crouch and get into the shaft underneath. You’ll need to locate a lift that works as a result though (new objective).
Head straight then right, through the broken glass-doors, and keep moving ahead. You’ll need to find a key-card to enter the morgue (look for a ‘Patient’s Room’).
Keep moving forward, and once you’re in the clear you can explore various rooms. There are also new weapons to pick up, such as a combat-shotgun dropped by enemies. Eventually you’ll come to a darker corridor which will lead you to the morgue itself; Alma will be appearing at different intervals here, it would be good to follow her since she leads you to where you need to be.
Once there you’ll need to move the trolley which is stuck between the lift doors (your action key). Congrats, the lift is now working and you can go to the third floor.
Now you’ll have to keep the action key pressed in order to open the stuck lift door. Go into ‘Office 202’ and find a door to another reception-area; there will be armed ops here so be alert. To the right of the vending-machine there is a door, where the ops have come from. Enter the door and keep going (you will still have to shoot your way through). You’ll reach a large lab full of hostiles; once this is clear keep going until you get to an elevator. There will be more soldiers, but when you are able to, you can now get into an open room with a staircase; go down the stairs and end the chapter.
